MQ resins that are suitable for use as component a), and also themethods for the production thereof, are known in the prior art. U.S.Pat. No. 2,814,601, belonging to Currie et al., of Nov. 26, 1957,incorporated into the present document by way of reference, describes amethod for the production of MQ resins by conversion of a water-solublesilicate into a silicic acid monomer or a silicic acid oligomer using anacid. Once the appropriate polymerization has been carried out,trimethylchlorosilane ends are introduced in order to obtain the MQresin. Another method for preparing MQ resins is described in U.S. Pat.No. 2,857,356 belonging to Goodwin, of Oct. 21, 1958, incorporated intothe present document by way of reference. Goodwin describes a method forthe production of an MQ resin by cohydrolysis of a mixture of an alkylsilicate and an organopolysiloxanetrialkylsilane which is hydrolysable,with water.

The MQ resins that are suitable as component a) in the present inventioncan contain D and T units, provided that at least 80 mol %, or even 90mol %, of the total siloxane units are M and Q units. The MQ resins canalso contain residual hydroxyl groups as is mentioned above. The MQresins can also comprise additional ends, residual hydroxyl groupsbeing, for this, reacted with suitable M groups.

The propyl T resin b) according to the invention comprises at least 80mol % of (R″SiO_(3/2)) units in which R″ independently represents analkyl group containing from 1 to 8 carbon atoms, an aryl group, acarbinol group or an amino group, with the condition that at least 40mol % of the R″ groups are propyl groups.

Preferably, the propyl T resin according to the invention is such thatat least 50 mol % of the R″ groups are propyl groups, preferably atleast 90 mol %.

Preferably, the propyl T resin b) is film-forming. The term“film-forming resin” is intended to mean a resin capable of forming, byitself or in the presence of an auxiliary film-forming agent, a filmwhich is macroscopically continuous and adherent to keratin materials,and preferably a cohesive film, and even better still a film of whichthe cohesion and the mechanical properties are such that it is possiblefor said film to be isolated and to be handled in isolation, for examplewhen said film is produced by pouring onto a non-stick surface such as aTeflon-coated or silicone-coated surface.

The definition of the R″ radical is the same as that of the R′ radical.The definitions mentioned above that are applicable to R′ are thusapplicable to R″.

The propyl T resin b) according to the invention is a silsesquioxaneresin. Silsesquioxane resins are well known in the prior art and aregenerally obtained by hydrolysis of an organosilane comprising threehydrolysable groups, such as halogen or alkoxy groups, present in themolecule. The propyl T resin b) can thus be obtained by hydrolysis ofpropyltrimethoxysilane, propyltriethoxysilane or propyltripropoxysilane,or by cohydrolysis of the abovementioned propylalkoxysilanes withvarious alkoxysilanes. As examples of these alkoxysilanes, mention maybe made of methyltrimethoxysilane, methyltriethoxysilane,methyltriisopropoxysilane, dimethyldimethoxysilane andphenyltrimethoxysilane. Propyltrichlorosilane can also be hydrolyzedalone, or in the presence of alcohol. In this case, the cohydrolysis canbe carried out by adding methyltrichlorosilane, dimethyldichlorosilane,phenyltrichlorosilane or similar chlorosilanes andmethyltrimethoxysilane, methyltriethoxysilane, methyltriisopropoxysilaneor similar methylalkoxysilanes. As alcohols that are suitable for thispurpose, mention may be made of methanol, ethanol, n-propyl alcohol,isopropyl alcohol, butanol, methoxyethanol, ethoxyethanol or similaralcohols. As examples of hydrocarbon-type solvents that can be usedsimultaneously, mention may be made of toluene, xylene or similararomatic hydrocarbons, hexane, heptane, isooctane or similar linear orpartially branched, saturated hydrocarbons; and also cyclohexane orsimilar aliphatic hydrocarbons.

The propyl T resins b) according to the invention may contain M, D and Qunits, provided that at least 80 mol %, or even 90 mol %, of the totalsiloxane units are T units. The propyl T resins may also containresidual hydroxyl and/or alkoxy groups, as is mentioned above.

The composition according to the invention also comprises aphysiologically acceptable medium. The term “physiologically acceptablemedium” is intended to mean a medium that is compatible with the skin,the mucous membranes and the skin integuments.

This medium may comprise at least one volatile silicone or organicsolvent, this solvent preferably being compatible with the resins a) andb) and compatible with cosmetic use.

As volatile silicone solvent, mention may be made of cyclicpolysiloxanes, linear polysiloxanes and mixtures thereof.

As volatile linear polysiloxanes, mention may be made ofhexamethyldisiloxane, octamethyltrisiloxane, decamethyltetrasiloxane,tetradecamethylhexasiloxane and hexadecamethylheptasiloxane.

As volatile cyclic polysiloxanes, mention may be made ofhexamethylcyclotrisiloxane, octamethylcyclotetrasiloxane,decamethylcyclopentasiloxane and dodecamethylcyclohexasiloxane.

The organic solvent may also be an alcohol, for instance ethanol,isopropanol, butanol, n-propanol; a ketone, for instance acetone, methylethyl ketone, or methyl isobutyl ketone; an aliphatic hydrocarbon, forinstance heptane, hexane, octane or isododecane, or a glycol ether, forinstance propylene glycol methyl ether, dipropylene glycol methyl ether,propylene glycol n-butyl ether, propylene glycol n-propyl ether, orethylene glycol n-butyl ether.

The mixture of resins a) and b) may be obtained from each of the resinsin solution in a solvent.

In general, at the end of synthesis of the MQ resin according to theinvention, this resin is obtained directly in solution in xylene.

Likewise, at the end of synthesis of the propyl T resin b) according tothe invention, this resin is obtained in solution in toluene.

Each of these resins in solution is mixed with the other one accordingto the following protocol:

-   -   1) the two resin solutions are mixed, with stirring, and then        heated, in particular in a reactor or in an autoclave (in order        to be able to carry out the operation optionally under pressure        or, on the contrary, by establishing a partial vacuum), or even        in an extruder optionally equipped with a solvent        “devolatilization” system, under the following specific        conditions:        -   uniform heating is carried out: the heating temperature            should be greater than 90° C., and less than or equal to            250° C., and preferably between 90° C. and 190° C.        -   Either the heating can be carried out at a single            temperature, of between 90° C. and 250° C.,        -   or the heating can be carried out by performing successive            temperature holds:        -   first between 90° C. and T1° C.,        -   T1° C. being a temperature having an intermediate value of            between 90° C. and T2° C. which is the final temperature,        -   for a period of time of between 10 minutes and 2 hours, and            then between 11° C. and T2° C., for a period of time of            between 10 minutes and 4 hours,        -   the temperature T2° C. corresponding to the maximum            temperature chosen for the reaction.        -   This value of T2° C. is variable according to the procedure            chosen and the type of reactor chosen: conventional reactor            or autoclave or extruder, but T2° C. remains less than or            equal to 250° C. It is also possible to perform intermediate            temperature holds between T1° C. and T2° C.;        -   the heating time is at least one hour in a reactor or in an            autoclave and at least 10 minutes in an extruder, preferably            between 1 h and 5 h in a reactor or in an autoclave, and            preferably between 10 minutes and 2 hours in an extruder;        -   provided that these heat treatments are carried out without            the presence of a catalyst for chemical condensation between            the two MQ and propyl T resins. Such a catalyst is in            particular a mineral base, in particular NaOH, KOH or            aqueous ammonia.    -   2) Optionally, after, or even during, step 1) of heat treatment        of the two resins in the temperature range indicated, partial or        total distillation of the aromatic solvents is carried out,        replacing them with a cosmetically acceptable volatile solvent.        Such a volatile solvent may in particular be a volatile        silicone, or not, preferably decamethylcyclopentasiloxane, or a        volatile organic solvent, or not, preferably isododecane.    -   3) Again optionally, after mixing of the two initial solutions        of each resin in a volatile solvent, the mixture of solutions is        treated in a screw or twin-screw blender of “devolatilizing”        extruder type, in a temperature range between 90° C. and 250°        C., making it possible to volatilize the volatile solvents by        establishing a partial vacuum, while working continuously, and        then to pass the molten mixture without solvent through a die.        The molten mixture is then cooled on leaving the die and cut up        in solid granules or in the form of a powder. In this case, the        mixture is directly in solid form and will be redissolved in the        selected solvents at the time of formulation.

Thus, a subject of the present invention is also a composition asdescribed above, comprising, in a physiologically acceptable medium:

1) the mixture of a siloxane resin a) and a propyl silsesquioxane resinb), the mixture being as described above, and

2) at least one volatile C8 to C16 hydrocarbon-based solvent,

the siloxane resin a) and the propyl silsesquioxane resin b) beingformulated in the composition via a mixture that can be obtainedaccording to the following method:

-   -   mixing, preferably with stirring, a solution of siloxane resin        with a solution of propyl silsesquioxane resin, the solvent        present in each of the solutions preferably being volatile, and        then    -   heating, in particular in a reactor or in an autoclave or in an        extruder, under the following specific conditions:        -   heating is carried out uniformly at a temperature of greater            than 90° C., and less than or equal to 250° C., preferably            between 90° C. and 190° C.; the heating can be carried out            at a single temperature, or at temperature holds, as            indicated above;        -   the heating time is at least 1 hour in a reactor or in an            autoclave and at least 10 minutes in an extruder, preferably            between 1 h and 5 h in a reactor or in an autoclave and            preferably between 10 minutes and 2 hours in an extruder;        -   provided that these heat treatments are carried out without            the presence of a catalyst for chemical condensation between            the two MQ and propyl T resins. Such a catalyst is in            particular a mineral base, in particular NaOH, KOH or            aqueous ammonia.

This method may comprise, after or even during the mixing step, anadditional step of partial or total distillation of the aromaticsolvents, replacing them with a cosmetically acceptable volatilesolvent.

When an extruder is used, this method may comprise, after or even duringthe mixing step, an additional step of partial or total distillation ofthe aromatic solvents, with the mixture exiting directly in the solidstate.

The final step of the heat treatment, or even the heat treatment itself,can be carried out in a blender intended for stirring very viscousmedia, such as:

-   -   a “Z-arm” blender (“Zigma blender”), in particular a Brabender        blender,    -   an extruder-type screw blender, in particular a single-screw        extruder or a twin-screw extruder (with or without a step of        “devolatilization” of the starting volatile solvents) or in a        kneader which makes it possible to devolatilize by establishing        a thin film on the walls.

Lipophilic Silicone Polymers:

The silicone polymeric lipophilic structuring agents are, for example,polymers of the polyorganosiloxane type, for instance those described indocuments U.S. Pat. No. 5,874,069, U.S. Pat. No. 5,919,441, U.S. Pat.No. 6,051,216 and U.S. Pat. No. 5,981,680. According to the invention,the polymers used as structuring agent can belong to the following twofamilies:

-   -   1) polyorganosiloxanes comprising at least two groups capable of        establishing hydrogen interactions, these two groups being        located in the polymer chain, and/or    -   2) polyorganosiloxanes comprising at least two groups capable of        establishing hydrogen interactions, these two groups being        located on grafts or branches.

The groups capable of establishing hydrogen interactions can be chosenfrom ester, amide, sulfonamide, carbamate, thiocarbamate, urea,urethane, thiourea, oxamido, guanidino and biguanidino groups andcombinations thereof.

These polymers are described in detail in application WO2003/106614 published on Dec. 24, 2003, the content of which isincorporated into the present application by way of reference.

The polymers and copolymers used in the composition of the inventionadvantageously have a solid-liquid transition temperature of 45° C. to190° C. Preferably, they have a solid-liquid transition temperatureranging from 70° C. to 130° C. and better still from 80° C. to 105° C.

Organogelling Agents:

The oily structuring agent may also be chosen from non-polymericmolecular organic gelling agents, also known as organogelling agents,which are compounds whose molecules are capable of establishing betweenthemselves physical interactions leading to self-aggregation of themolecules with formation of a supramolecular 3D network that isresponsible for the gelation of the oil(s) (also known as the liquidfatty phase).

The supramolecular network may result from the formation of a network offibrils (caused by the stacking or aggregation of organogellingmolecules), which immobilizes the molecules of the liquid fatty phase.

The ability to form this network of fibrils, and thus to gel, depends onthe nature (or chemical class) of the organogelling agent, on the natureof the substituents borne by its molecules for a given chemical class,and on the nature of the liquid fatty phase.

The physical interactions are of diverse nature but excludeco-crystallization. These physical interactions are in particularinteractions of self-complementary hydrogen interaction type, itinteractions between unsaturated rings, dipolar interactions,coordination bonds with organometallic derivatives, and combinationsthereof. In general, each molecule of an organogelling agent canestablish several types of physical interaction with a neighboringmolecule. Thus, advantageously, the molecules of the organogellingagents according to the invention comprise at least one group capable ofestablishing hydrogen bonds and better still at least two groups capableof establishing hydrogen bonds, at least one aromatic ring and betterstill at least two aromatic rings, at least one or more ethylenicallyunsaturated bonds and/or at least one or more asymmetric carbons.Preferably, the groups capable of forming hydrogen bonds are chosen fromhydroxyl, carbonyl, amine, carboxylic acid, amide, urea and benzylgroups, and combinations thereof.

The organogelling agent(s) according to the invention is (are) solublein the liquid fatty phase after heating to obtain a transparent uniformliquid phase. They may be solid or liquid at room temperature andatmospheric pressure.

The molecular organogelling agent(s) that may be used in the compositionaccording to the invention is (are) especially those described in thedocument “Specialist Surfactants” edited by D. Robb, 1997, pp. 209-263,Chapter 8 by P. Terech, European patent applications EP-A-1 068 854 andEP-A-1 086 945, or alternatively in patent application WO-A-02/47031.

Mention may be made especially, among these organogelling agents, ofamides of carboxylic acids, in particular of tricarboxylic acids, forinstance cyclohexanetricarboxamides (see European patent applicationEP-A-1 068 854), diamides with hydrocarbon-based chains each containingfrom 1 to 22 carbon atoms, for example from 6 to 18 carbon atoms, saidchains being unsubstituted or substituted with at least one substituentchosen from ester, urea and fluoro groups (see patent application EP-A-1086 945) and especially diamides resulting from the reaction ofdiaminocyclohexane, in particular diaminocyclohexane in trans form, andof an acid chloride, for instanceN,N′-bis-(dodecanoyl)-1,2-diaminocyclohexane, N-acylamino acid amides,for instance the diamides resulting from the action of an N-acylaminoacid with amines containing from 1 to 22 carbon atoms, for instancethose described in document WO-93/23008 and especially N-acylglutamicacid amides in which the acyl group represents a C₈ to C₂₂ alkyl chain,such as N-lauroyl-L-glutamic acid dibutylamide, manufactured or sold bythe company Ajinomoto under the name GP-1, and mixtures thereof.

In another embodiment, one of the radicals R or R′ represents a linear,branched and/or cyclic, saturated or unsaturated C₁-C₃₀ alkyl radical,optionally comprising 1 to 3 heteroatoms chosen from O, S, F and N.

Materials

MQ resin=an MQ resin of formula M_(0.43)Q_(0.57) and of M_(n)=3230dissolved in xylene at 70.8% by weight of solids. The MQ resin wasproduced according to the techniques described by Daudt in U.S. Pat. No.2,676,182.

Propyl T resin=a propyl silsesquioxane resin at 74.8% by weight intoluene. The propyl silsesquioxane resin was obtained by hydrolysis ofpropyl trichlorosilane.

Various solutions of MQ resin and of propyl T resin are mixed in athree-necked flask equipped with a stirrer. Aliquots of each mixture areplaced in an aluminum dish 2 inches in diameter, and heated under vacuumat a temperature of 110° C. for one hour, followed by 1 h 25 at 140° C.Visual qualitative observations regarding the clarity and the hardnessof the mixtures obtained are made (see table 1 below):

TABLE 1 % by Propyl T Dried aliquot weight of Example # MQ (g) (g)Aliquot (g) (g) MQ resin Clarity Hardness 1-a 0.00 13.46 2.0475 1.53610.0 Clear Gum appearance; soft solid 1-b 1.40 12.03 2.0643 1.5415 9.9Clear Soft solid 1-c 2.88 16.74 2.0840 1.5517 14.0 Clear Harder than 1-b1-d 4.19 9.39 2.0746 1.5414 29.7 Clear Harder than 1-c 1-e 5.72 8.142.1066 1.5606 39.9 Clear Harder than 1-d 1-f 7.11 6.82 2.0257 1.496849.6 Clear Harder than 1-e

The results obtained show the unexpected miscibility of the MQ resin andthe propyl T resin, based on the clarity of the mixture without solventand the increasing hardness as the amount of MQ resin increases.

Procedure

The constituents of phase A3 are weighed out. The mixture is passedthrough a triple roll mill.

The constituents of phase A1 are then weighed into the main beaker andit is placed in a waterbath (75-80° C.). When the mixture ishomogeneous, the constituents of phase A2 are added. After stirring for5 minutes on a Moritz stirrer at 1500 rpm, the mixture is cooled toambient temperature.

A3 is incorporated into the phase A1+A2, with stirring on a Moritzstirrer at 1500 rpm.

The constituents of phase A4 are then added successively, while keepingthe same stirring.

The constituents of phase B are weighed out. Phase B is brought toboiling, until complete dissolution of the constituents. Phase B iscooled to 50° C.

Phase B is then trickled into the phase A1+A2+A3+A4, with stirring on aMoritz stirrer at 3200 rpm. The stirring is maintained for a minimum of10 minutes.

Protocol for Instrumental Measurements of the Immediate Color andStaying Power of the Color

A colorimetric measurement of the skin is carried out before and afterapplying makeup by measuring the red, yellow and brightness indices,respectively a*, b*, L*. For each woman, an image is taken using achromasphere, with a definition of 410×410 pixels.

The results are expressed in the following way. The color is quantifiedby the red, yellow and brightness indices analyzed by the camera(respectively a*, b*, L*). The staying power of the color is calculatedby the variation in these variables after the makeup has been worn for 3hours (deltaE94).

More specifically, the measurements are carried out on a panel ofindividuals who are kept in an air-conditioned (22° C.+/−2° C.) waitingroom for 15 min before the beginning of the test. They remove theirmakeup and an image of one of their cheeks is acquired using thechromasphere with a definition of 410×410 pixels. This image makes itpossible to measure the color at TO before applying makeup.Approximately 100 mg of cosmetic composition are then weighed out into awatch glass and are applied with the bare fingers to the half of theface on which the TO measurement was carried out.

After a drying time of 15 min, an image of the made-up cheek is acquiredusing the chromasphere. This image makes it possible to measure thecolor immediately after applying makeup (Timm). The models then returnto the air-conditioned room for 3 h. Finally, an image of the made-upcheek after waiting for 3 h is acquired using the chromasphere. Thisimage makes it possible to measure the color after wearing makeup for 3h (T3h).

The results are expressed by calculating the difference (Timm−T0), whichmeasures the effect of the makeup. The difference (T3h−Timm) measuringthe staying power of this effect is then calculated. Each image obtainedusing the camera is made use of in color. The color is quantified by thered and yellow indices, the brightness and the color difference(respectively a*,b*,L and deltaE). The deltaE, dE or else ΔE is definedas a measurement of difference between two colors. The formulaestablished in 1976 is shown below:|ΔE*=√{square root over (((L ₁ −L ₂)²+(a ₁ −a ₂)²+(b ₁ −b ₂)²)}{squareroot over (((L ₁ −L ₂)²+(a ₁ −a ₂)²+(b ₁ −b ₂)²)}{square root over (((L₁ −L ₂)²+(a ₁ −a ₂)²+(b ₁ −b ₂)²)}|where:

-   -   L₁, a₁ and b₁ are the coordinates in the colorimetric space of        the first color to be compared and L₂, a₂ and b₂ those of the        second.

Protocol for Instrumental Measurements of the Immediate Mattness and thePersistence of the Mattness

Protocol for instrumental measurements of the immediate mattness and thepersistence of the mattness The mattness effect and staying power of themattness of the application, to the skin of a panel of individuals, ofthe W/O emulsion described above is evaluated. The mattness and thestaying power of the mattness can be measured by means of the protocoldescribed hereinafter. The mattness of a region of the skin, for exampleof the face, is measured using a polarimetric camera, which is a blackand white polarimetric imaging system, with which images are acquired inparallel (P) and crossed (C) polarized light. By analyzing the imageresulting from the subtraction of the two images (P-C), the shine isquantified by measuring the mean level of gray of the 5% of shiniestpixels corresponding to the regions of shine.

More specifically, the measurements are carried out on a panel ofindividuals who are kept in an air-conditioned (22° C.+/−2° C.) waitingroom for 15 min before the beginning of the test. They remove theirmakeup and an image of one of their cheeks is acquired with thepolarimetric camera. This image makes it possible to measure the shineat T0 before applying makeup. Approximately 100 mg of the compositiondescribed above are then weighed out into a watch glass and are appliedwith the bare fingers to the half of the face on which the T0measurement was carried out.

After a drying time of 15 min, an image of the made-up cheek is acquiredwith the polarimetric camera. This image makes it possible to measurethe shine immediately after applying makeup (Timm). The models thenreturn to the air-conditioned room for 3 h. Finally, an image of themade-up cheek after waiting 3 h is acquired with the polarimetriccamera. This image makes it possible to measure the shine after wearingmakeup for 3 h (T3h). The results are expressed by calculating thedifference (Timm−T0), which measures the effect of the makeup. Anegative value means that the makeup reduces the shine of the skin andthat it is thus mattifying.

The difference (T3h−Timm) measuring the staying power of this effect isthen calculated. The value obtained should be as low as possible, whichmeans that the mattness of the makeup does not change over time.

Protocol for Instrumental Measurements of the Immediate Uniformity andStaying Power of the Uniformity

A colorimetric measurement of the skin before and after applying makeupis carried out by measuring the means for the planes a* (green-red),b*(blue-yellow), L*(brightness). For each woman, an image is taken usinga chromasphere with a definition of 410×410 pixels. More specifically,the measurements are carried out on a panel of individuals who are keptin an air-conditioned (22° C.+/−2° C.) waiting room for 15 min beforethe beginning of the test. They remove their makeup and an image of oneof their cheeks is acquired using the chromasphere with a definition of410×410 pixels. This image makes it possible to measure the color at TObefore applying makeup. Approximately 100 mg of cosmetic composition arethen weighed out into a watch glass and are applied with the barefingers to the half of the face on which the measurement was carried outat TO.

After a drying time of 15 min, an image of the made-up cheek is acquiredusing the chromasphere. This image makes it possible to measure thecolor immediately after applying makeup (Timm). The models then returnto the air-conditioned room for 3 h. Finally, an image of the made-upcheek after waiting for 3 h is acquired using the chromasphere. Thisimage makes it possible to measure the color after wearing makeup for 3h (T3h).

Each image obtained using the camera is made use of by coxellography.The standard deviation of each monochrome plane is calculated. Theproduct of the three standard deviations is equal to the coxellographicindex. This parameter is used for the statistical calculations. The moreuniform the skin, the lower the standard deviation. The coxellographicindex changes in the same way since it is the product of the standarddeviations of the three planes a*, b* and L*.

Staying Power Results

For the measurements carried out, it is considered that:

-   -   + slight effect or low staying power    -   ++ moderate effect or moderate staying power    -   +++ significant effect or good staying power    -   ++++ very significant effect or very good staying power

Composition D exhibits a mattifying effect at Timm which is very highcompared with the other compositions, and a mattness staying power whichis judged to be moderate at 3 hours (but greater than that ofcomposition B). In comparison with formulation C, which has betterstaying power but much less of a mattifying effect at Timm, the mattnessat 3 hours is equivalent.

After 3 hours, the color staying power is excellent on this formulation,and significantly better than that of composition C. The uniformingeffect is low but has very good staying power over time.

According to these results, it can be argued that there is good overallstaying power (in terms of mattness, color and uniformity), with a levelof mattifying which is much greater than that of compositions A, B andC.

Sensory Evaluation Results (Makeup Application in the Laboratory)

On application, compositions B and D dry less quickly than the othercompositions.

Composition A catches during application and dries too quickly. Asensation of rubbing is felt on the skin, which makes the applicationuncomfortable and unpleasant.

Composition B does not dry too quickly, but crunches under the fingerson application. It gives a result which is perceived as satin-like oreven shiny.

Composition C dries more quickly. It is thicker under the fingers,presents more material.

Composition D emerges as being finer on application, with betterglidance. Application is easy with no “crunching” effect on the skin.The product glides perfectly under the fingers, which makes applicationpleasant.

The combination according to the invention (composition D) thereforemakes it possible to provide good staying-power properties (inparticular color and uniformity) with a very high level of mattifying,and very good cosmetic performance levels.
